Application filed December 12 1918. Serial No. 266,444.

To all whom it may concern Be it known that I, ESTER M. SEALY, a citizen of the F ort-Shafter, in the Territory of Hawaii, have invented certain new and useful Improvements in- Underscorers for- Typewriters, of which the following is a specification.

This invention relates to underscorers for typewriters, and more particularly to a device by means ofwhich predetermined words maybe underscored simultaneously with the typing operation.

a means therefor,

' One of the main objects of'the invention is to provide a device of the character stated of simple construction and operation by means of which words which are written in first case or second case letters may be easily underscored simultaneously with the typing thereof. A further object is to provide an underscorer which may be readily applied to a type,writing machine of standard construction. Another object is to provide an underscorer and means in connection therewith for moving the underscorer either into or out of operative position, means also being provided for moving the underscoring element into positionto underscore either first case or second case letters simultaneously with the shifting of the carriage or key board for this purpose. Further objects will appear from the detailed description.

In the drawings:

The typewriter A may be of any suitable construction and is provided with the usual carriage B slidable thereon and havin the platen roll D paper guide (land assoclated parts. In front of the roll is mounted a 1'0. vided the usual fork ribbon guide F. This guide is provided with the usual central slot across which is passed the ribbon H taken from the spoolsIin the usual manner. The typewriting machine illustrated and the parts thereof referred to, are all of standard construction, the particular machine shown being what is known on the market as the Royal typewriter. V

A rod 1 is mounted beneath the key board and the associated parts of the typewriter and extends the full length of the machine.

This rod is reduced at gudgeon 2. These gudgeons fit into cooperating recesses or bores 3 formed in' supporting screws 4 which are threaded through theend' lates 5 of the frame of the typewriter. y this means, rod 1 is detachably secured in the typewriter and is mounted therein for rocking movement about an axis extending longitudinally of the machine. A sleeve 6 is secured on rod 1 adjacent one end thereof. .by means of a set screw 7 threaded through the sleeve and engaging the rod. A coil tension spring 8 is mounted about the end portion of the rod adjacent the outer end of sleeve 6 and has one end bent substantially at right angles to provide a fingei"9 which engages into a cooperating recess in the adjacent endof the sleeve. The

each end to provide a outer end portion of spring 8 is straightened to provide an arm .10 having at its outer end a finger ,11 disposed substantially at right angles thereto, this finger engaging into the of the typewriter frame. Spring 8 acts to rock sleever6 forwardly and upwardly and, through the sleeve, also serves to cause similar movement of rod 1. Sleeve6 is provided with an integral'forwardly projecting lever 12. This lever is provided 'atits outer or forward end with an integral upwardly directed finger 13 at the upper-end of which is secured F 1g. 9 is a section taken substantially on ver 15.

an operating head or key 14. A releasing lever 15 is pivotally secured at' its inner end to lever 12, intermediate the ends thereof, by means of a screw or pin 16. Releasing lever 15 is normally held in raised position by a wire spring 17 which engages about the,

lever in advance of the pivotal axis thereof, the inner end of this spring being engaged about the lower edge portion of lever 12.

substantially rectangular finger or stud 18 is carried by the lever 15 adjacent the inner end thereof and, being positioned in front of the spring, serves to prevent displacement of this member when the releasing lever is rocked; Lever 15 is provided, at its outer end, with a standard19 at the upper end of which. is secured a head or key 20. The upward movement of lever 15 under the influence of spring 17 is positively limited by a stud 21 carried by lever 12 and engaging the upper edge of lever 15. As will be noted, lever 15 projects forwardly beyond lever 12 and engaging the upper edge of le- As will be noted,.lever 15 projects forwardly beyond lever 12 so as to permit andfacilitate independent operation thereof. Lever 12 is provided, at its lower forward corner, with a substantially V- shaped head 22 having the forwardly projected point 23 the upper face of which is disposed in parallelism with lever 12 and is adapted to.be engaged b the head 24 of a pawl 25 which is rockalily mounted on a stub shaft 26 which projects from the adjacent end plate 5 of the typewriter frame.

This pawl is normally forced inwardly tothe forward downwardly ward lever 12 by a wire spring 27 coiled about the bearingsleeve 28 which supports stub shaft 26, the inner portion of this spring bearing against the forward or outer face of pawl 25, and the outer end of'this spring being secured in end late 5. When operating lever 12 is rocke downwardly, and inwardly in clined face of point 23 will engage the 1111181 end of the head 24 of the pawl so as to rock the pawl outwardly. Ale soon. as the upper edge of head 24 is. moved into coincidence with the upper'surface' of the head of the pawl, the pawl will be moved inwardly so as to bring the head thereof above point 23, thus locking lever 12 in de ressed position, as in Fig.7. When it is esired to release the lever, this is accomplished by depress ing the releasing lever 15 so as to bring the lower edge of the intermediate downwardly and inwardly inclined portion 15 into engagement with the inner end of head 24 of the pawl. lhis results in rocking the awl 25 outwardly such a distance as'to re ease lever 12 which is then returned to its initial position by tension spring 8. Whenthe' lever 12 is raised, head 24 of the pawl will engage a depending lug 29 provided at the lower end of 15, the shaft the ll-shaped head 22 of the lever 12 for this purpose. Thislug isso related to lever 12 as to maintain'the pawl in the position illustrated in Fig. 9 when the operating lever is in' raised position so that, when the operating lever is depressed,- the pawl will be rocked inwardly so as to engage over the point 23 of head 22 in the manner previously described. By means of the operating lever 12 and releasing lever 1 may be rocked a predetermined distance in either direction, and secured in rocked adjustment, as will be obvious. Y

A collar 30 is loosely mounted 'on the rod 1 at the longitudinal center thereof. This collar is normally rocked forwardly and downwardly by means of a coil tension spring 31 which is mounted about rod 1 adjacent one end of'the collar, one end of this spring being secured in one end of collar 30 as at 32, the other end of the spring being secured to the rod by means of a screw 33, or in any other suitable manner. A collar 34 is secured on rod 1 by means of a set screw 35 and'is positioned closely adjacent the other end of collar 30'. 1 Collar 34 isprovided, at its inner end, with an integral axially extending lug 36 which projects into an arcuate groove or recess 37 formed in the adjacent end of collar 30. This lug serves to positively limit rotary movement of collar 30 in either direction relative to collar 34. By" means of set screw 35, collar 34 may be secured in rotary adjustment on the rod so as to vary the portion of rod 1 about which sleeve 31 is rocked. An arm 38 is formed in tegral with sleeve. 30 and projects rearwardly therefrom. The rearward end of this arm is, bifurcated to form a fork 39. Whenthe rod 1 is rocked downwardly'and forwardly, lug 36 will be moved out of engagement with sleeve 30 at the rearward end of slot 37 thus permitting the sleeve to be rocked downwardly and forwardly under the influence of spring 31. By this means, when. operating lever-12 is depressed and locked in this osition, the arm 38 will be rocked upwar ly and resiliently held in.

through an eye 42 provided at the lowenend of the connecting rod 41 which is inserted through an eye 42 provided at the lower end of the-connecting rod 43, red to the arm pin and slot connections. A substantiall rectangular or cubical securing block 4; is secured'on the upper end of rod 43. "This block is provided, on its inner face, with a central rib 48 and has a central bore 49 adapted to receive the shank of a securing screw 50. Screw 50 is adapted Law! thus securing the provided through the body 52 of the underliner52adjacent the lower end thereof. The block 47 coiiperates with a securing plate 53 end of rod 43, the rib plate 53, the

positioned adjacent the inner face of the body of the underliner. This plate is pro-' vided with a central recess of slot extending the full width thereof-which is adapted to snugly receive the lower end portion'of the shank'of the underliner and the rib 48 of b'lock47. Securing screw 50 is inserted through block 47 and threaded through the block and plate coiiperating to rlgidly secure the underliner to the upper and the slot in plate 53 effectually preventing all looseness or play of the underliner. As will be noted more clearly from F igs. 1 and 2, the slot 51 is of greater length than the rib 48 thus permitting independent vertical adjustment of the underliner rendering it possible to secure very accurate setor adjustment of this member. Securing plate 53' is provided, at its lower end, with a finger 54 formed integral therewith. This finger projects beneath theupper horizontal arm 46 of stop bar 46 and serves to positively limit upward movement of rod 43 and consequently,

the underliner carried thereby. Arm 54 projects through the alined slots 55 and 56 As will be noted more clearly from Fig. 13

' body portion 47 of block 47 is. reduced to form lateral flanges 47 at the outer end of the block, and plate 53 corresponds in width to the outer end of the block. The plate and block thus coiiperates to produce a guide head having lateral vertical grooves .which receive the edge portions of the guide plate 61 secured on supporting plate 57 in front of the ribbon guide F, plate 61 being provided with a central slot 61 whichreceives the guide bar, the head and plate coiiperating to guide and brace the underscorer during its vertical movement.

Underliner 52 is provided, at the upper end of shank 52 thereof, with a rectangular or substantially jects forwardly shank. The inner this head is beveled striking or marking element 59, and the outer end of the outer arm is straight and disposed in parallelism with the shank.

and rearwardly of the end of the inner arm of Head 58 is of such-length that, when the.

When the type bar 62 of the typewriter is raised by means of the key in the usual manner, P 5 tioned between type head63 of the type ba'r the head 58 of the underscorer will be and the platen roll so as toihav'e'jthe outer end ofarm 60 enga type head, thus forcing thema'rkingelement of the drawings, the

ged by the bar 64 (if-the scorer as mounted on at the inner end to produce a short line on the paper being typed upon. As stated a stop bar 46 acts to positively limit upward movement of the underscorer. This stop baris carried by the carriage of the typewriter which, in the particular typeof machine illustrated, is operated by the usual shift key so as to be raised or lowered according to whether it is desired to use first case or second case letters. When the operating lever 12 is in normal or raised position, the arm 38 is rocked downwardly and rearwardly so asto maintain the underscorer in inoperative or lowered position, where it will not be struck by the type head 63 of a type bar 62, as illustrated in Fig. 6.

When lever 12 is secured in depressed position, the underscorer will be raised into such strike head 58 so as to 'simultaneouslycause pIarticu- L the production of a line beneath the lar letter which has been struck. n this manner, any desired letters or words may be underscored simultaneously with the typing thereof. This operation is illustrated in Fig. 7. When the carriage is raised so as to cause the first case letters carried by the first case letter block 66 tostrike the platen, the underscorer will also be raised by means of spring 31 due to the fact that the stop bar 46 is raised with the carriage. The underscorer head 58 will now occupy a position intermediate the letter blocks 65 and 66 when the ty e in'Fig. 8. 0 permit proper operationof the underscorer when in this position, I 67 through shank ,52 adjacent the head 58, this opening being so positioned as to permit the letter block 65 tolpass therethrough when type head 63 is raised, as illustrated. By thls means a line is produced-beneath the capital or first case letter which is typedsimultaneously with thetyping, of said letter, In Figs. 6 to 8 inclusive, illustrating the three stages of operation. of the underscorer, the ribbon guide, ribbon, and associated parts, and the papers being typed confusion an moreclearly illustrate the operation of the mechanism.

In the particular form of mechanism illus have shown the stop bar-for limiting the upward moyement of the underthe carriage, this car'- riage being adjusted vertically to change bar-is operated, as illustrated.

u on has been omitted to avoid i from one case to the other.

In machines where the key board is\shifted instead of the carriage, the stop members would of course, be connected to 'the key board so as to move therewith. In either case, the operation ofthe mechanism will be the same.

' of and in the mechanism, and I intend to in accordance with underscorer,

include in this application all such variations, as fall within the appended claims, and donot desire to be limited to the specific construction illustrated except in sofar as limitations may be imposed by the claims.
